Smart Code Completion

IntelliJ IDEA offers the most intelligent code completion for all supported languages,
including Java, Scala, Groovy, JavaScript, HTML, CSS, Ruby, Python, SQL, PHP and many others. The IDE
analyzes the
context and suggests the best completion option, with no additional action from you. With IntelliJ IDEA, you
can code faster than you think.

Instant Completion

Instant code completion means you get a suggestion without doing anything.
Completion choices appear just as you type. This type of completion speeds up coding significantly.

Advanced Completions

IntelliJ IDEA provides multiple completion techniques based on the context and user needs.

While basic completion helps you complete names of classes, methods, fields, and keywords within the
visibility scope.
Smart completion, on the other hand, suggests only those types that are expected in the current
context.
